摘要
在新能源产业日益发展的背景下,新能源输出的波动性对区域电网平衡和能源消纳提出了重大挑战。因此,本文提出了新能源一体化条件下跨区输电功率波动预测方法。综合考虑新能源出力波动、容量置信度、调峰特性参数等因素,结合数值天气预报数据,构建了具有代表性的综合样本数据集。对样本数据进行归一化处理,消除参数之间的维度差异。采用麻雀搜索算法优化双隐层 BP 神经网络的权值和阈值,有效避免了过度训练导致的局部优化问题。实验结果表明,该方法在预测新能源跨区消纳和输送过程中的功率波动方面具有显著优势,预测功率与功率比超过 0.85。
Prediction method for power fluctuations in cross regional consumption and transportation under the integration of new energy
Against the backdrop of the increasing development of the new energy industry, the volatility of new energy output poses significant challenges to regional power grid balance and energy absorption. Therefore, this article proposes a prediction method for cross regional transmission power fluctuations under new energy integration conditions. A comprehensive and representative sample dataset was constructed by comprehensively considering factors such as fluctuations in new energy output, capacity confidence, and peak shaving characteristic parameters, combined with numerical weather forecast data. Normalize the sample data to eliminate dimensional differences between parameters. The sparrow search algorithm is used to optimize the weights and thresholds of the double hidden layer BP neural network, effectively avoiding local optimization problems caused by over training. The experimental results show that this method has significant advantages in predicting power fluctuations in cross regional absorption and transportation of new energy, with a predicted power to power ratio of over 0.85.
